Is my approach to this kind of excercise completely off the track??

I'm getting errors like "I entered Zimmerman and expected to be on line 2" or something.

Thanks in advance!

ConferenceRegistrationAssistant.java 
public class ConferenceRegistrationAssistant {

  public int getLineFor(String lastName) {
    /* If the last name is between A thru M send them to line 1
       Otherwise send them to line 2 */

    int line = 0;

    if('A' < 'M') {
      line = 1;
      return line;

    } else {
      line = 2;
      return line;
    }

  }

}

Hey there Marc, you were super close on this looks like just a little logic control flow, which is a one line fix.

When comparing the characters you have it set up to see if 

if ('A' < 'M' )

which is always going to be true, so line one will always be returned.

With that being said, change that line.

if (lastName.charAt(0) < 'M')

I did this using your exact code and it passed with flying colors.

Good job! Shoot back if it's still giving you trouble.

Hey Rob,

thank you for your great advice! The course didn't tell anything about the charAt() function.

Hey Rob I tried yours but I still get errors. My code is like this below import java.io.Console; public class ConferenceRegistrationAssistant {

public int getLineFor(String lastName) { /* If the last name is between A thru M send them to line 1 Otherwise send them to line 2 */ Console console = System.console(); lastName = console.readLine("enter your last name"); char Name = lastName.charAt(0); if(Name < 'm'){ line = 1; return line; } else{ line = 2; } }

}
